Webmaster tool crawl error - Not Found

[webfreebie]

Guys,
When my default page is .../index.htm, it shows I have 404 (Not found) problem with .../index.html.
I changed my default page to .../index.html. I also changed my internal links to ../index.html or .../. It then shows I have 404 (Not found) problem with .../index.htm.

And now I have two errors. Anybody had the same problem?

The dots are the problem. Home links should go directly to the domain root itself - ideally "http://www.example.com/" or, second best IMO, simply "/"

One possibility is that someone has linked to your site using the wrong extension. Also, when you made the changeover, you might not have changed all the internal links.

Tedster, thanks, but i didn't really use those dots. I used "http://www.example.com/index.html".

Canonicalize the whole shebang back to the root... Problem solved:

RewriteEngine on
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/]+/)*index\.html?
RewriteRule ^(([^/]+/)*)index\.html?$ http://www.example.com/$1 [R=301,L]

Modified Code from jdMorgan in the Apache Forum [webmasterworld.com].

Yes. Add the above code to your .htaccess file and make sure you link to exactly "/" or to "http://www.example.com/" every time.
